Part N of my continuing saga.
A few months back I wrote of my problems getting dialing working with an
ATA. Two ATAs later, I have given up and replaced all the hardware. It
is now a standard PC (Celeron 1.2GHz) running "Asterisk Now" 1.0.2 with
a cloned TDM410 (1 FXO) PCI card talking to my analog phone line, and
various (SIP and Unistim) phones inside.
Part of the complexity was and still is that we have an ALDS (Alt. L.D.
service) that we activate by dialing 10 digits, waiting for dialtone,
and dialing the actual 10-digit number.
There is some progress. I can fairly reliably have Asterisk dial numbers
both locally and over the ALDS. Incoming calls still work; this has
never been the problem.
But everything involving dialing from the phones while connected is
unreliable. E.g., dealing with IVR-based voicemail, scheduling, etc.
The setup, now, is
Analog ---- TDM400 FXO -- Asterisk -- internal phones
Most of the phones are on a full-duplex switch, because that is
providing POE for several of the phones.
Here is part of the sip.conf for one of the SIP phones:
[general]
realm=XXX
disallow=all
allow=ulaw
localnet=192.168.1.0/24
; Grandstream BT100 phone
[31]
type=friend
secret=XXX
context=internal
nat=no
host=dynamic
canreinvite=no
qualify=yes
mailbox=20
dtmfmode=rfc2833
The GS phone has these settings:
Send DTMF: in-audio X via RTP (RFC2833) via SIP INFO
DTMF Payload Type: 101 (that was the factory default)
-------------------------
Here is the zapata.conf:
[trunkgroups]
[channels]
; default
; usecallerid=yes
; hidecallerid=no
; callwaiting=no
; threewaycalling=yes
; transfer=yes
; echocancel=yes
; echotraining=yes
; increased, to let sending work.
toneduration=300
; last resort
relaxdtmf=yes
; define channels
context=incoming
---------------------------------
Unistim.conf isn't shown but it has no settings related to DTMF;
these phones always communicate over a local LAN and always send DTMF
out of band (according to chan_unistim anyway)
---------------------------------
And here's the local and ALDS dialing macros:
PSTN_DIALER=Zap/1
[macro-dial-outbound-local]
exten => s,1,SetCallerID("Darwin" <905-XXX-XXXX>)
exten => s,n,Dial(${PSTN_DIALER}/${ARG1},20)
exten => s,n,GotoIf($["${DIALSTATUS}" = "BUSY"]?busy:unavail)
exten => s,n(unavail),Congestion()
exten => s,n,Hangup()
exten => s,n(busy),Congestion()
exten => s,n,Hangup()
[macro-dial-outbound-worldline]
;exten => s,1,Dial(${PSTN_DIALER}/${WORLDLINE_ACCESS},10,D(wwwww${ARG1}))
exten => s,1,Dial(${PSTN_DIALER}/${WORLDLINE_ACCESS}wwwwww${ARG1}))
exten => s,n,GotoIf($["${DIALSTATUS}" = "BUSY"],busy)
exten => s,n(busy),Congestion()
exten => s,n,Hangup()
---------------------------------------
Summary: dialing via either of these macros works, but anytime we send
DTMF from any keypad, it's unreliable. Dialing "9" by itself, for
example, dials Worldline's number, where sending 10 digits should work.
I wonder if this is related to why the first attempt at
dial-outbound-worldline didn't work?
Using an analog phone on the same phone line works 100%, btw.
Thoughts? Further information needed?
Many thanks if you can help.
